BUT if there is a serious issue in the houses built by following the project you had signed, well, you will go to jail (or pay the fine).
I still have to see a software engineer held PERSONALLY accountable, in front of the law, for a PII leak, for example.
I think it depends on the type of work (and also legislation). For example I had architects calculating which kind/size of iron girder/joist (IDK the exact English word for it) put to replace a supporting wall. If they calculate that badly, the roof comes down at some point, and I die.
